$\frac{4}{5}$

Work Step by Step

Factor each term then eliminate any factors that are common to numerators and denominators. Multiply numerator by numerator and denominator by denominator. $\frac{3}{x}\times\frac{4x}{15}=\frac{\big/\!\!\!3}{\big/\!\!\!x}\times\frac{4\times\big/\!\!\!x}{\big/\!\!\!3\times5}=\frac{4}{5}$
